Here is one of my physics homework problems I have to do:

An unusual variant of basketball is played on the planet Zarth. During the game, a player flies above the basket and drops the ball in from a height of 14.3 m.

If the ball takes 4.7 s to fall into the basket, what is the acceleration due to gravity, g, on the planet Zarth?

😆 gotta love my physics teacher 🙄

so what's the answer 🥷

eww...

I guess you can take the average velocity.

I got: 0,64735174287007695789950203712087

Whichs ounds slightly reasonable.

Listen here protoss girl, either you help solve this problem, or i'll send you and your zealot butt with the xel'naga

You mean 0.64735174287007695789950203712087 right?

I got 1.294703486 m/s/s

I think

a = Average Velocity/time

Average Velocity = 14.3 m / 4.7 s

Time = 4.7 s

But I might be wrong.

Well, maybe, how did you calculate it?

I think

a = Average Velocity/time

Average Velocity = 14.3 m / 4.7 s

Time = 4.7 s

But I might be wrong.

They give you DeltaX-14.3 and they give you T-4.7

The formula is X=.5gt^2

So pluggin it in I got 14.3=.5g(4.7)^2

Isolating the "g" I got 1.2947...*plugs it into computer program* and I'm correct w00t

Though Mr. Bacon is right. I couldn't calculate final nor initial velocity though.

you need the formula with distance, i forget it

What formula is that?

nice

It's one of the free falling equations

see:

Yes, that makes sense.

Oh, I see I forgot to take it times two. Well close, though not good enough.

Here's another, not as funny but really hard:

Tina the ballerina leaps into the air during her dance practice.

How long does she remain in the air if she jumps straight up with a speed of 1.71 m/s?

EDIT: It uses the second eqution realizing that vf=-vi
